...I like your comment about the bonfire....
We have had quick look at some of the products used by some of the larger institutions/organisations but we didn't find many and those we found weren't cheap, sometimes 4 figures for the product and then annual licence fees well into the hundreds....niche market I guess...guess it might be back to the box of index cards...
